Google is preparing the next-generation Nexus 7 tablet that may debut in May.

According to BGR, the next Nexus 7 will reportedly debut in May as a "cooperative effort with manufacturing partner Asus."

Unnamed sources from within Google's supply chain claimed that the Nexus 7 tablet will feature a tweaked design and a full 1080p high-definition display.

"The bezel around the screen will be narrower as well according to the report, and the tablet will supposedly run an "upgraded Jelly Bean-based Android operating system to enhance integration between the software and the hardware." According to the site's sources, combined first- and second-generation Nexus 7 shipments are expected to total 10 million units this year," the BGR report said.

In terms of price, the next Nexus 7 will be similar to the ones that Google is currently charging for the Nexus 7, according to CNET, which is $199 to $249. The report also said that Google might announce the new product at its annual I/O developer conference in May. It may run on Android 4.2 Jelly Bean or the next version of Android, codenamed Key Lime Pie.

According to T3.com, the next-generation Nexus 7 will have a thinner design with a much thinner bezel "which would make the device smaller to carry and would almost certainly reduce the weight as well."

Rumors started flying around about another cheaper Nexus 7 tablet in 2012.

According to CNET, Google and Asus are working on a tablet that will be priced lower than $150, going as low as $99. Digitimes first reported it, citing sources at display component maker O-Film Tech.

The low-priced Nexus 7 tablet should be released by the second quarter of next year. O-Film started shipping components for the device in December. The touch-screen glass-glass film technology will contribute to lower production costs and make it thinner, CNET said. Shipment estimates of the new Nexus 7 are in the range of 500,000 to 600,000 in the first quarter of shipments.

The leaked specs say that the cheap Nexus 7 will run on Android 4.1.1 on 1 Ghz CPU. It has a 400MHz Mali GPU with 1,024 x 600 screen resolution. It will have 1GB of RAM, a 1MP front-facing camera and a microSD card slot.

This doesn't seem like the same Nexus 7 tablet that may be announced soon in May, but we will just have to wait to find out.
